HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 241,343, dated May 10, 1881.

Application filed February 14, 1881.

.th'e points where the calks are located, of calks having threaded stems secured into said sockets, and locking-plates of iiexible metal interposed between the proximate surfaces of the shoe and calks, suitably attached to the shoe to prevent them from turning, and provided with tongues or ears bent over the edges of the calks to prevent the latter from turning in their screw-sockets.

The invention also consists in certain details of construction, all of which I will now proceed to describe and claim.

Of the accompanying drawings, forming' a part of this specification, Figure 1 represents a view of the under side ot' a horseshoe, showing thelocking-plates before their ears are bent over the calks. Figs. 2, 3, and 4 represent, respectively, sections on lines x 00,1/ y, and zz, Fig. 1. Fig. 5 represents a view of the under side of the shoe with the calks attached and secured by the locking-plates. Figs. 6, 7, and S represent, respectively, sections on lines m m', y y', and c c', Fig. 5; and Figs. 9, 10, 1l, 12, and 13 represent views of parts in detail.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention I provide a horseshoe with screw-sockets a a a, one for each calk, and I provide each calk b with a screw-stem, c, projecting from its upper or shoe bearing-surface, and adapted to be screwed into one of the sockets a. The calks may be ot' any suitable form. I prefer to make each T-shaped in cross-section, with a broad hoot' bearing-surface and a narrower tread or rib, b2, the hoot` bearing-portion projecting in the form of shoulders b b in each side of said rib.

(No model.)

The stem c forms au integral part ofthe calk, and when the latter is made of cast iron or steel, as I prefer, the stem c may be first made with an enlarged head, secured to the calk by embedding the head in the calk while the latter is being cast. The head of the stem may be slotted, so that when the calk is worn out and the cast metal is removed from the slot the stein may be unscrewed.

d represents a locking-plate, which is made of steel or other flexible metal, and is interposed between the proximate surfaces ot' the shoe and the calk. The plate d is prevented from turning' on the shoe by asuitable attach ment therewith, and this attachment may be a screw or screws, f, (see Fig. 1,) or the projectin g end ot' a block, g, hereinafter described, said end fitting closely in an oritice, lt, in the plate, and preventing the same from turning. It' desired, both of the described means may be used, especially for the toe-calk, which is usually longer than the hcel-calks, as shownn Fig. 1. The plate d has one or more projecting tongues, ,formed upon it, and these tongues are adapted to be bent over upon the edges of the lianges b b of the calk b, as shown in Figs. (i and 8, and act as stops to prevent the calk from turning. The calk is preferably provided with recesses m, to receive the tongues t', said recesses being of such depth that the outer surfaces ofthe tongues are tlush with the surfaces of the iianges b when said tongues are bent. The block g, before mentioned, is of tapering form, as shown in Fig. 12, and the socket a is formed in this block. The block is inserted in a correspoudingly-shapcd recess, o, formed in the shoe, as shown in Fig. 9. The object of making the socket a in a block in this manner is to enable a blacksmith to more expeditiously provide a shoe with said sockets, which are to be made by machinery, like ordinary nuts. Hence the workman is saved the labor of cutting threads in the shoe, and has only to form the orifices o, which are easily made. The block g is somewhat longer than the thickness ofthe shoe, so that one of its ends will project for the purpose of entering the oritce k in the plate d, as already described. The larger end of the block g is at the ripper or hoof bearingsurface of the shoe, so that the said block is drawn tirmly to its seat on the tapering sides lcalk is subjected to strain.

of the recess by the operation of screwing the calk into the socket.

Besides the T-shaped calk already described, I also make use of the modification shown in Figs. 14 and 15, the first-named figure representing a top view of a toe-calk, and the other a section on the line 1 1, Fig. 14. In this modification the calk is approximately L-shaped, provided with a shoulder, b, on the back side only, having therein two recesses, m m, to receive the tongues of the locking-plate. In this form of calk the shoulder b is somewhat broader than in the form previously described. In other respects the calk is made and applied as before set forth.

It is evident that the calk b and the plate d may be iliade in large quantities by suitable machinery, and supplied to dealers as articles of manufacture, so that a blacksmith can obtain said parts, as well as the blocks g, and apply thein to any ordinary horseshoe, the only adaptation ofthe shoe required being the foi-ni ation of the oriliees 0. The orifice o being once formed, any person not a blacksmith may purchase said parts,the saine being madein various sizes to fit any size of shoe, and can apply them himself without resorting to a blacksmith. When a calk is once attached and locked it will be seen that it cannot be removed without cutting or bending back the ears 'i 1T, and I prefer to form these ears to dovetail into the recesses m m, as when so formed they are less likely to be drawn out of said recess when the When the calk iS removed the plate d may be readily removed, and a new plate and calk may be applied without removing the shoe from the horses foot.

Having thus described my invention, what I claim is- 1. The combination of a horseshoe, a calk attached to the shoe by a threaded stein or bolt, and a locking-pl ate of flexible metal interposed between the proximate surfaces ot' the shoe and cal k prevented from turning by a suitable attachment to the shoe, and provided with a projecting tongue or tongues bent over upon the sides of the calk to prevent the latter from turning, as set forth.

2. A horseshoe having a threaded calk-stemreeeiving socket, and a flexible metal plate attached to its under surface, and provided with a tongue or tongues adapted to be bent over upon the sides of acalk secured into said socket to prevent the calk from turning, as set forth.

3. The combination of a horseshoe havinga block projeetin g below the lower surface of the shoe and containingascrew-socket, a calk having a threaded stem screwed into said socket` and the lexibleinetal locking-plate interposed between the shoe and the calk, and provided with an orifice fitting closely on the pi'qjectii'ig end ofthe block, said projecting end preventing the plate from turning, as set forth.

In testimony whereof I have signed my naine to this specification, in the presence of two subseribing witnesses, this 10th day of February, A. D. 1881.
